Wifi Off Windows 8.1

[PraiseTheSun]

Hello, hopefully some of you can lend me a hand here. I bought an Acer Aspire M3-581T ultra book the other day and I thought it would be nice to install 8.1 rather than 7 since it had a fresh drive and the mSSD had been cleaned. I'm quite fond of 8 but still run 7 on my gaming rig. Anyway the point is that my wireless is labelled "OFF". It's been like that since I installed 8.1. All my drivers were pulled down from windows update and all seem fine until I notice the wireless tab said off. I tried to remove them and download them with no success. I even went to the Acer website and downloaded the drivers manually and every time I tried to install it, it would get so far before coming up with a blue screen that labels something along the line of thread not handled. Any suggestions?

-Yes I extracted the drivers.
-I tried setup as well as pointing windows to the driver software
-plentiful reboots
-No more updates available
-Tried updating driver through device manager.
-Tried FN keys to enable wireless.
-No physical wireless switch

Please help 🙁🙁

Did you try installing the Driver using Compatibility Mode? Rt click the setup.exe file and choose 'Troubleshoot Compatibility' then 'Troubleshoot Program' and choose earlier version etc. Win 7...

Blue screened again, same error, system_thread_exception_not_handled or something. Do you think installing 7 on a separate partition and getting the wireless going on that could maybe do something for me?

Doubt that's the answer! Take it your Wireless Adapter is the driver you're having probs with? I had the same with an older HP laptop, ended up buying wireless dongle, uses up a USB port, I know, but they are so small they don't get in the way

One last, did you install all the drivers for your rig? Sometimes the Fn keys driver is hidden in an obscure d'load....
And it won't do any harm to check out the integrity of your OS
First try System File Checker
Winkey plus 'X'
Choose Command Prompt (Admin)
Type sfc /scannow then Enter

It finds and fixes errors in Windows, but doesn't always report them. Run it and see if the fault disappears after re-booting your system
If corrupt files are found that can’t be fixed, try

Dism /Online /Cleanup-Image /RestoreHealth

Re-run SFC

To view CBS Log

findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >sfcdetails.txt

Search C drive for sfcdetails.txt or navigate to C:\Windows\System32 and scroll down.

Tried installing 7 and same issue. I'll system file checker. Didn't think of that. Thanks for the answers! I'll reply back to you when the file checkers done

Hmmm. If it happened with 7 perhaps we're looking at a hardware issue, are you able to post the full stop code?

 

[PraiseTheSun]

Right SFC and the restore health didn't cut it.
I know it used to work wireless before I reinstalled it but maybe when it got opened up something happened.
Could you point in the direction to find the stop code so I copy paste it to you? Thanks

 

[PraiseTheSun]

The wireless tab is locked on off and is greyed out. I tried to download acer launch manager but noting seemed to have changed :/

All it says is SYSTEM_THREAD_EXCEPTION_NOT_HANDLED. Don't know if it's any use to you

A bit generic! Could be a number of causes. Does your Adapter appear in Device Manager?

 

[PraiseTheSun]

Yes it does. Good news, I managed to resolve this issue by doing something I overlooked. All I did was reset the bios and it worked. Sorry for all your time, can't believe I overlooked it. Thank you very much! Is there anything I can do to give you +1 or something on this forum. I'm not a very experienced toms hardware poster!

Also I have no idea how to close this thread or mark as solved 😛

Long as you fixed it! Did you restore defaults, or remove CMOS battery?

 

[PraiseTheSun]

Just a reset, didn't take the cmos out. Thanks for being really helpful and patient.

You're welcome. By reset presume you mean 'Restore Defaults' (F9 or similar) just in case anyone else has a similar problem...

 

[PraiseTheSun]

Yeah, just load default values (F9) and then save and exit (F10)
Started up and boom, it found my wireless network straight away

[brisa]

thanks!! thanks!! so many thanks!!
I've had this problem with my laptop for more than 2 years now, and I never never never would thought it was BIOS problem. We change SO, network card, everything.. I had to use a wifi dongle with an awful signal level...

BUt now, thanks to you, I have again the factory wifi

THanks

 

[nameer kp]

hi buddies just press fn+f2.it will work 100000000%

 

[tiger2shadow]

thank u so much man i want to kiss u for solving this

 

[fubared79]

FN+F2 didnt work for me. seems when I connect to my 5ghz connection it randomly happens. I went to device manager and found my wireless network. Disabled it then enabled it and my wifi was up for me to select a connection! Hope this help

 

[SKISLAL]

I have a Lenovo Z570 I had to do a Windows format today. I tried everything. I had the same problem as you. WIFI was off. As a last resort, I defaulted BIOS settings (except SATA/AHCI). When I restarted the PC, WIFI was surprisingly on. Posting here so the solution may be useful for others too.
